Chanukah is an 8 day holiday so you would wish people a 'chag channukah sameach' on any of those 8 days.
Chanukah starts on the Hebrew calendar date of 25 Kislev, and lasts for eight days. Here are the coinciding secular dates for the upcoming years:
2011: December 20-28
2012: December 8-16
2013: November 27-December 5
2014: December 16-24
2015: December 6-14
Yes.
You shouldn't. Hanukkah and Christmas are no necessarily on the same day, so it would be inappropriate to wish someone a happy Hanukkah on December 25, if that day isn't during of Hanukkah. A better idea would be to look on a calendar to see when Hanukkah falls, then then wish your Jewish friends a Happy Hanukkah on Hanukkah.
Hanukkah is a holiday. Not a language. During Hanukkah you would say "hello" the same as on a regular day. You can also greet people by saying "Happy Hanukkah".
